Well, its more than just that, in my opinion. Besides, they could always use

Most people in the world do not currently think too far beyond their own
borders; of those who do, most do not think beyond the script that is
generally used in their borders.

Sure, Unicode lets the big companies ship products to all of those people --
but the average person does not care that their copy of Word can handle a
ton of languages, anyway!

One of the great things about 10646 and Unicode being in sync is that there
are some people who do not trust industry -- so they can just embrace ISO.
Others do not trust anyone but the actual people doing the implementing --
they can embrace Unicode.
